Thank you for the comment.

As usual I did not have a time to create tutorial so everything was written in the description of the game algouth I am aware that not many people read it or it does not have to be clear for many people. 

I am going to do tutorial next time. (I already know I am lying to myself. :D)

You have to "blow" the current more -> meaning each press and release create one current of the wind. More currents = more power. Then it is going to move.
